Abstract
An inexpensive, easy to assemble patch antenna is disclosed where unwanted polarizations in the transmitted RF energy are minimized. A feedboard, spacer and resonator are held in a compressed relationship by two halves of the antenna housing. The spacer is a thermo-formed sheet with semi-spherical spacers. The spacers have a height that provides the desired spacing between the feedboard and the resonator.
